Average snow-cover duration, 1998 - 2007

Snow-cover duration and snow-cover extent, which can both be measured from satellites, have decreased. There is less certainty about changes in snow depth because this has to be measured on the ground, so the observations are less extensive. This map show how the number of days with snow cover has changed between 1972 and 2008, as measured every week from images taken by satellites.
